Work load control Monark 891 E
Monark Ergomedic 891 E is a test device, applied
with a braking system, where the brake force can be
adjusted with weights on a weight carrier. Weights are
available in 0.1 kg / 2.2 lb, 0,5 kg / 1.1 lb and 1,0 kg
/ 0.2 lb. This allows the brake load to be varied with
0.1 kg. NOTE! 0,1 kg is the minimum weight, which
is the weight of the weight carrier. The weight basket
can also be set in its upper free/resting position and
does then not give any work load at all. Disengage the
basket by pushing the knob(1). See Fig: Adjustments.
Power measurement
The cycle is designed to measure the power on the
flywheel, because tests/protocols are made for it (for
example Åstrand’s and YMCA).
Settings
To adjust the height on the support stand pull the
handle(2) outwards. Turn the handle clockwise to
raise the stand and counterclockwise to lower it.

A person's heart rate can be measured with a chest
belt that senses the electronic output of the heart. The
chest belt is standard equipment.
Fuss-free HR measurement requires that the belt is
correctly placed. When it is correctly fitted the logo
on the belt will be central and readable, outward
and upright, by another person. Before putting on
the belt, clean the skin where the belt is to be placed.
The chest belt should be secured at a comfortable
tension around the mid section, just below the breast
muscle, see Fig: Placement of the chest belt. Moisten
the electrodes before use, see Fig: Electrodes on the
back of the chest belt. To make contact with the HR
receiver on the bike, the distance should not be more
than 100 cm. It is especially important when first used
to identify the chest belt with the sensor, by standing
close to get the HR (maximum 60 cm).
NOTE! Electromagnetic waves can interfere with the
telemetry system. Cellular phones are not allowed to
be used near the bike during test.
